"Brainphone...?"

"Telepathic phonelike thing?" says Shell Bell. "It's very handy, do you want in? I've already added Jarvis to announce myself when I first arrived, you could talk to him wherever without making a sound."

"Gimme," says Tony. "That would be very useful."

[Behold!]

[Ooooh,] says Tony.

[It also does text channel. And busy messages that pop up according to arbitrarily complicated algorithms, although since in this world I've only added you, Jarvis, and Darcy, I don't think you'll need those unless you want me to throw a dozen of your friends in too.]

He laughs. [My friends all have real phones.]

[This is more convenient. You can't lose it, it works underwater and in loud environments, and it's free. But as you like.]

"See," he says, "I'd have to explain it to my friends."

"You got the idea quick enough," she points out.

"The mechanics aren't the problem, the backstory is."

"Darcy's not bored yet. I could help."

"Help how?" he inquires.

"Appear to them - now with new and improved anti-nudity algorithms - introduce myself, ask them if they want brainphones?" she shrugs. "Is there some non-obvious other way I could be of help?"

"Well, Pepper's still asleep," he says, waving a hand in the direction of the bedroom. "And God knows where Rhodey is, probably in a plane, he's been known to fly those."

"It's not like I can't teleport onto a plane," Bell points out. "Pepper? That's a cute name."

"Says a woman named Shell Bell," Tony snorts. "You rhyme."

"My real name is Bell. The shell part is a nickname. Remember how I was bringing shells into Milliways since I was six? It doesn't warn me when it's going to give me a door, and having shells on my person or not was the difference between staying three days, starving, or staying three weeks, getting a reasonable meal every day and more time to learn things and look for some magic or tech I could take home and be that little bit safer. I left bags of clamshells near every door I ever went through and pitched a fit if someone moved them. The rhyme just made it even more obvious."

"...Yeah," he says, "I mean, I figured? Pepper's a nickname too, her real name's Virginia."

"How is Pepper a nickname for Virginia?" asks Bell.

"That is a very good question," says Tony, "and I came up with it, so I should know the answer."

"...But you don't?"

"Nope."

"Huh. Anyway, do you want me to go see about talking to your friend who might be on an airplane?"
